In Australia, a cube is also a commonly purchased quantity of beer. A cube consists of 30 cans (not bottles), each holding 375 ml. Sold in cubes are the cheaper, more mainstream brands of lager. Exactly what these brands are varies from city to city and state to state, but brands commonly sold in cubes include Victoria Bitter, Carlton Draught, Toohey's Red and Boags Classic Bitter.

Cubes are popular among bogans and uni students, for two reasons. The first is that a cube costs between 30-35 dollars (AUD), meaning that this is an incredibly cheap, although not the absolute cheapest, way of getting messily drunk without making your own. The second reason is that two or three people can go on a ten or fifteen minute there-and-back walk to the bottle-o and will still have at least a slab remaining by the time they get back.
